I've never had a problem with the way 7MC manages TV recordings. As mentioned, you can sort (and group) recordings in many ways, and get thumbnails in the preview as well. It's slick, neat and reliable. I also use MB, and have some TV shows that were TV recordings in there as well. I keep a seperate folder on my WHS (TV Shows), then subfolders with the series name. I then just rename the .wtv file to something more appropriate (e.g. showname.S01E01.wtv), and scrape the metadata. Shows up in MB and plays fine through the 7MC internal player.
If you use WHS and the PP3 Win7 connector, then you also have the option of archiving favorite TV shows to the server (manually or automatically), so you can have you recordings in two places. Once you do this, any 7MC PC around the house can view them as well.
